that the feeding operation can be carried on and drum or by any other suitable means.

Thus the end portion of the wire will become coiled about the drum 2 and will be formed into large coils by the bending rolls 9, 10 and 11. g

The wire is also extended between the rolls 13 and 15 and passes therefrom into and through the furnace (not shown) and thence to the header or other machine. The operation of the machine will cause the wire to be pulled longitudinally through the furnace and off of the rotating drumQ. The mechanism is so constructedthat the wire will be fed to drum 2 slightly faster than-it is withdrawn therefrom. Obviously, therefore, the coils" supported by the drum 2 will slowly increase in size with the result that, as the end of the wire approaches drum 2 it becomes possible to stop the supply of Wire to said drum without stopping the, feeding of wire through the furnace to the forming machine. This is due to the fact that rolls and 16 can be shifted away from the drum 2 and the continued feeding of the wire while the supply of wire to the drum is discone tinned will result in the taking up of slack in'the coils on the drum 2 and during this period of operation another coil of wire can be placed on the reel 1 and the forward end thereof connected to the rear endof the used coil by means of clamps or by welding. This operation can be completed before all of the slack on drum 2 has been taken up and withcan then be returned into engagement with the wire and drum 2 and the new supply of wire will be fed to the drum'2 and to'the furnace or the forming machine in the manner continuously and all delays due to temporary stopping will be eliminated.

It will be understood of course that the rolls 13 and lo can operate to take off the stock at any speed independently of the operationof the drum 2 and in, some instances can be entirely displaced by the forming machine.

As before stated this mechanism is designed primarily for use in feeding stock from a coil through a furnace and thence to a forming machine but it will be apparcut that the same mechanism can also be employed in connection with cold headers or other machines where no furnace is used.

Among these'may be mentioned cold nut machines, spring making machinery, wire nail machines, and any. other type of machinesto which stool: is fed from a coil. In every instance the feeding mechanism of the machinery to which this invention is ap plied constitutes ameans for pulling the material from the feeding mechanism herein disclosed but where a furnace is used for heating the materialthe rolls 13 and 15 also The rolls 5 and Thus it will be seen thereof used in the claims can apply either to the rolls 13 and 15 or to the ordinary feed ing mechanism of a header or the like.

Whatisclaimed is:

1. Feeding mechanism of, the class described including a drum mounted for rotation, having a peripheral groove, a rotatable annularly grooved roll cooperating with the grooved drrun for gripping and guiding material directed therebe-tween, material pulling mechanism, and means for operating the same to withdraw material from the drum at a lesser speed than it is supplied thereto.

2. Feeding mechanism of the class described including a drum, a roll rotatable therewith, a second roll, said rolls cooperating'to grip material and coil it about the drum, means for supporting said rolls for movement into or out of operative relation with the drum, thereby to feed or discontinue feeding material, respectively, and rel atively movable rolls for engaging material and withdrawing it from the drum at a lesser speed than it is supplied thereto.

3. The combination with a structure for use in forming material, of mechanism for directing into said structure a continuously mova-ble, unbroken supply ofmaterial, said mechanism includinga support for coiled material, pulling mechanism for said material, feeding means for actuating the pulling mechanism, and means engaging the material for directing it into the pulling mechanism faster than it is fed by the pullin mechanism to the structure, thereby to buil up a surplus of material between the pulling mechanism and the feeding means whereby one end of the material can be held and connected to one end of another length of material during the continuance of the feeding operation.

4. The combination witha structure for usein forming material, of mechanism for directing into said structure a continuously movable,unbroken supply of material, said mechanism including a reel for holding coiled material, a pulling mechanism for feeding the material continuously to said structure, and feeding means interposed between the reel and the pulling mechanism for building up and supporting a surplus of material between the pulley mechanism and v the reel whereby one end of the material can be held andconnected to one end of another length of material during the continuance of the feeding operation. v

5. The combination with a structure for use, in forming materiahof means for simul taneously feedingmaterial to said structure and building up a surplus of material Whereby one end of the material can be held and Welded to one end of another length of ma terial during the continuance of the feeding operation, said means including a reel for supporting a supply of coiled material for rotation a pulling mechanism for engaging the material to feed it continuously to the structure and means for directingmaterial from the reel toward the pulling mechanism at a greater speed than the speed at Which the mate-rial is fed to the structure by the pulling mechanism, thereby to build up coils of surplus material between the reel and the pulling mechanism.

In testimony that We claim the foregoing as our oWn, We have hereto aflixed our signatures.
